(ol. 301-9) Thisinventionfrelates to aidemountable wheel displacement. VVVThis lparticular mounting for the mounting and lock, an object of the invention disk is, of course, capable of modificatiomgthe being to provide improved means f-orxsupporting one lessential feature being that the disk "have and locking a demountable wheel whereby the rotary or turning movement Within certain limits ;5 wheel can be -quickly removed and replaced by in the center of the drum 5, andv in 'order to an authorized person with a proper tool. v limit this turning movement a post 11 isv fixed vA further object isto provide an article-of this to the drum and projects vthrough 'an arcuate character which dispenses Vwith the use of ordislot 12 in the disk. j i nary nuts and 'screw-threaded bolts, and which The cylindrical wall 13 of the drum 5 is pro- ,10 provides asinglev member which when turned in vided with acircular series'of open sleeves 14 in :110' rone direction projects a series of radial bolts into which bolts `15 are mounted. These bolts 15 are coupling engagement with a supporting drum and eachconnect'ed by links 16 with the disk 7, `said Wheel hub, and when moved in the opposite direclinks having pivotal connection with the bolts, tion retracts all of Asaid bolts so` that the wheel Vas illustrated at 17, and pivotal connection with i5-may be readily removed. p l the disk, as lillustrated at 18.

These 'plungers 21 are 40 trating the lock. I y preferably mounted inlbarrels 23 xed to the 40 1 represents the axle of a vehicle, such as an drum 5, with coil springs 24 in the barrels back automobile, to which a brake drum 2 is in fixed of the plungers so that when the disk isturned l l relation as, rfor examp1e, by means of a sleeve 3 to looking or holding position these plungers will on the brake drum receiving the axle 1 and spring into the open sockets 22 and hold the disk; keyed thereto, as shown at 4. 5 represents our hence, before the disk can be turned to retract 45 improved Wheel supporting drum which is open the bolts 15 and release the wheel it isr necessary atfits front or outer portion and is closed at its that these plungers 21 be forced inwardly. To inner portion, and may be secured to the drum accomplish this, we employ a lspecial type of 2 by rivets 6 or other securing means. A` disk 7 Wrench 25. This wrench 25 has a prong 26 at l is mounted to turn centrally in the drum 5 and one end adapted to 'enter an eye 2'7 fixed to the 50 we have illustrated one means ofmounting this disk adjacent one edge thereof and fulcrum in drum, which consists of providing the same with said eye. The wrench 25 has a central opening la central opening 8 receiving the cylindrical re- 28 to accommodate the axle 1, or more specifiduced outer portion 9 of the sleeve 3 with the cally the nut 29 screwed onto the end thereof, member 10 on the sleeve holding the disk 7 against and at opposite sides the wrench is formed with 55 pins k30 which are adapted tol enter the sockets 22, and when the Wrench is fulcrumed forcethe plungers 21 inwardly to release the disk, and

, while holding the plungers in this position the wrench can be turned to turn the disk and retract the bolts.

' To prevent the possibility of theft a removable lock 3l may be provided Which locks into kone of the sockets 22 and cannot be removed except by the insertion of the proper key. Hence, when this lock is in one of the sockets the Wrench cannot be used and the disk cannot be turned to retract the bolts.

In order to facilitate the proper positioningof" the Wheel hub 19 on the drum, so that the nipples will align or register with the sleeves 14, the drum, or more specifically the cylindrical'vwall `13 thereof, may be formed with'a notch 32 receiving` an enlargement or key 33 on the wheel hub;

hence, when the operator places the Wheel hub fon the sleeve hesimply turns this hub until the key or enlargement 33 registers with the notch 32, and then he can press `the hub completely on -the drum and be sure that the bolt receiving members are in proper alignment. It is comparatively easy to turn the wheel afterit is inserted on the drumso that it is a simple and easy operation to properly align the parts.A

v j While we have described our improved mounting inconnection with the axle of an automobile Vit is, of course, to be understood that the same arrangement of mounting would be Iutilized' to care for the sparewheel; that is to say, the fifth drum would be utilized at theibackof the automobile or elsewhereito support, receive and lock the spare` wheel so that'it may be connected vand disconnected whenever.` occasion may require. 4VWhile we have illustrated What we believe to ,be the preferred embodiment of our invention, it is tobedistinctly understood that various slight l Lchanges may be made with regard toV the form and arrangementv of parts without departing from our'invention, and hence We do not limit ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

What we claim is: i 1. l wheell mounting including a drum, a wheel, a hub on the wheel adaptedrto t the drum, aplurality of radially positionedbolts supported onthe drum and adapted to be projected into the hub to secure the hub and the drum toi gether, a rotary member inthe drum, links connecting the rotary member and bolts ywhereby the turning movement of the rotary member servesto project or retractlthe bolts, aspring- .pressed plunger in the drum, a socket in the ro'- Itary member receivingl said plunger when the rotary member is in a position to project the,

bolts, so that before said rotary member can be turned to'ret'ract the bolts 'the' plungenmist` be withdrawn, and a removable `lock located in the socket which must 'be removed to yaiford access to thel plunger. g

2. A wheel vmounting includingy a drum, 'a wheelja hub on thewheel ttingthe drum, means on the hub land Wheel for centeringthe hub on the drum,-locking means'between the :hub andthe Wheel,` a disk mounted to turn in' the -drum` and operatively vcontrolling the Ilocking means, a pair'of open sockets atv opposite sides of the disk, spring-pressed plungers adaptedi'to spring into the sockets when the disk is in locking position, and an eye on the vdisk adapted vto receive a wrench or operating member to permit the? wrench to fulcruni to engage Vthe spring# its turning movement.
